AhpCp1000

Introduction

We improve the function of a BioBrick Part: ahpC promoter(Part:K362001)designed by [http://2010.igem.org/Team:KIT-Kyoto/Parts 2010 KIT-Tokyo team] into 6 versions.On PartRegistry, the complex part(according to [http://ecocyc.org/ECOLI/new-image?object=EG11384 Ecocyc]) composition contains hybrid promoters, shared TFBS (Transcription Factor Binding Site), and reverse promoter DsbG. In this part AhpCp1000, we succesfully mutated the Pst1 site (ctgcag->ctacag) of ahpC promoter(Part:K362001).

Mutation of ahpC promoter(Part:K362001)

ahpC promoter, as well as its improvement, can be activated by OxyR(Part:BBa_K1104200).

Illustration of OxyR Activation

OxyR, a positive regulator of hydrogen peroxide-inducible genes in E. coli. The OxyR transcription factor regulates the H₂O₂ response of E. coli. H₂O₂ oxidizes OxyR Cys199 to an R-SOH that reacts with Cys208 in an intramolecular disulphide bond.

Structure of the OxyR Regulatory Domain
(A)Reduced Form: Inactive
(B)Oxidized Form: Activated by ROS
